[0021] Embodiment 1, as shown in Figures 1-4 and Figure 9 shown, the present application provides a soft tape quick-connect joint, comprising: The first connecting piece 1, a first through hole 11 is provided on the first connecting piece 1, one end of the first connecting piece 1 is provided with a connecting plate 12, a first thread part 10 is also provided on the first connecting piece 1, and the first through hole 11 also penetrates through the connecting plate 12; The second connecting piece 2, a second through hole 21 and a second thread part 211 are provided on the second connecting piece 2; The second connecting piece 2 is connected to the first connecting piece 1 through the cooperation of the second thread part 211 and the first thread part 10, and a clamping and sealing space is formed between the second connecting piece 2 and the connecting plate 12.

[0022] The clamping and sealing space is configured to clamp the pipe wall of the main water supply pipe; In addition, at least one first annular rib 15 is provided on the surface of the connecting plate 12 of the first connecting piece 1 opposite to the second connecting piece 2, and the first annular rib 15 surrounds the outer periphery of the first through hole 11; and / or, at least one second annular rib 22 is provided on the end surface of the second connecting piece 2 opposite to the connecting plate 12, and the second annular rib 22 surrounds the outer periphery of the second through hole 21.

[0023] Specifically, the soft belt quick-connect joint in the present application is assembled by the first connecting piece 1 and the second connecting piece 2. Among them, the first connecting piece 1 and the second connecting piece 2 can be assembled into an opening 31 provided on the main water supply pipe 3 through mutual cooperation, so that the water in the main water supply pipe 3 can flow out through the first through hole 11 and the second through hole 21, and an irrigation branch pipe is connected to the second connecting piece 2. In this way, the water flowing out from the second through hole 21 will enter the irrigation branch pipe and flow to the corresponding irrigation area.

[0024] Among them, since the first connecting piece 1 and the second connecting piece 2 clamp the main water supply pipe 3 by means of threaded connection, the clamped part of the main water supply pipe 3 needs to achieve good water tightness. For this purpose, a first annular rib 15 can be provided on the connecting plate 12 of the first connecting piece 1. Similarly, a second annular rib 22 can also be provided on the second connecting piece 2.

[0025] After connecting the first connecting piece 1 and the second connecting piece 2 together and clamping the pipe wall of the main water supply pipe 3, the first annular rib 15 and / or the second annular rib 22 will be pressed more tightly against the pipe wall of the main water supply pipe 3. In this way, a good water sealing treatment can be carried out on the clamped part of the main water supply pipe 3.

[0026] Further, taking the second connecting piece 2 provided with the second annular rib 22 as an example, the improvement of the second annular rib 22 on the sealing treatment of the opening 31 will be described.

[0027] On the end face of the second connecting member 2 opposite to the connecting plate 12, there is a protruding second annular rib 22. After connecting the second connecting member 2 to the first connecting member 1 and clamping the pipe wall of the main water supply pipe 3 between the two, the second annular rib 22 will further press against the outer pipe wall of the main water supply pipe 3. At the same time, the second annular rib 22 is also distributed around the periphery of the opening 31. In this way, by using the second annular rib 22 to further compact the pipe wall around the opening 31 on the connecting plate 12, the second annular rib 22 effectively improves the sealing performance of the opening 31.

[0028] Wherein, according to needs, a plurality of second annular ribs 22 can be arranged on the end face of the second connecting member 2, and the plurality of second annular ribs 22 are arranged concentrically; Between two adjacent second annular ribs 22, it is configured to form an outer sealing area on the pipe wall of the water supply pipe.

[0029] Specifically, the plurality of second annular ribs 22 tightly press the pipe wall of the main water supply pipe 3 on the connecting plate 12. Between two adjacent second annular ribs 22, an outer sealing area with good sealing performance will be formed. The outer sealing area surrounds the opening 31 to improve the sealing performance of the periphery of the opening 31.

[0030] Similarly, in the case where the connecting plate 12 is provided with the first annular rib 15. A plurality of first annular ribs 15 are arranged on the connecting plate 12, and the plurality of first annular ribs 15 are arranged concentrically; Between two adjacent first annular ribs 15, it is configured to form an inner sealing area on the pipe wall of the water supply pipe.

[0031] In an embodiment of the present application, the representation entities of the first threaded portion 10 and the second threaded portion 211 can have various forms.

[0032] For example: the first threaded portion is a first external thread segment formed on the outer peripheral circle of the first connecting member; the second threaded portion is a first internal thread hole formed at one end of the second through hole; wherein, the first external thread segment is threadedly connected in the first internal thread hole.

[0033] Or, the first threaded portion is a second internal thread hole formed on the inner wall of the first through hole; the second connecting member is further provided with an extension portion, the second through hole also penetrates through the extension portion, and the second threaded portion is a second external thread segment formed on the outer peripheral circle of the extension portion; wherein, the second external thread segment is threadedly connected in the second internal thread hole.

[0034] In another embodiment, there can be various forms of connection between the first connecting member 1 and the main water supply pipe 3. For example, the first connecting member 1 can be adhesively bonded or welded to the inner pipe wall of the main water supply pipe 3 through the connecting plate 12. Alternatively, the first connecting member 1 can be rotatably inserted into the main water supply pipe 3 from the outside through the opening 31 of the main water supply pipe 3.

[0035] As Figures 5-8 shown, the connecting plate 12 of the first connecting member 1 is fixedly connected to the inner pipe wall of the main water supply pipe 3 by welding. Since the connecting plate 12 is welded to the inner wall of the main water supply pipe 3, and the main water supply pipe 3 is an overall flexible pipe body, and the main body structure of the first connecting member 1 is located at the opening. In order to ensure that when the main water supply pipe 3 is wound and unwound, the main body structure of the first connecting member 1 is not stressed to cause the connecting plate 12 to be severely separated from the inner wall of the main water supply pipe 3, a bent connecting portion 16 can be further provided between the outer peripheral circle of the first connecting member 1 and the connecting plate 12. The bent connecting portion 16 has an annular structure, and an annular groove is formed in the bent connecting portion 16.

[0036] Specifically, the first connecting member 1 is generally made of a plastic material. Therefore, the bent connecting portion 16 has a certain elastic deformation ability. After the connecting plate 12 is welded to the inner wall of the main water supply pipe 3, when the main water supply pipe 3 is wound, even if the main body structure of the first connecting member 1 is stressed, the amount of deformation of the main body structure of the first connecting member 1 can be buffered by the bent connecting portion 16 to ensure that the connecting plate 12 and the main water supply pipe 3 maintain a good welded connection state. In this way, when laying the pipeline on site and connecting the second connecting member 2, the situation where the first connecting member 1 falls off inside the main water supply pipe 3 is reduced, thereby improving the use reliability.

[0037] Embodiment 2, as Figures 10-16 shown, the present application provides a soft belt quick-connect joint. The first connecting member 1 is rotatably inserted from the opening 31 of the main water supply pipe 3. The following specific description is made in conjunction with the accompanying drawings.

[0038] The soft belt quick-connect joint includes: A first connecting member 1, a first through hole 11 is provided on the first connecting member 1. One end of the first connecting member 1 is provided with a connecting plate 12. An insertion portion 13 extending outward is provided at the edge of the connecting plate 12. A first thread portion is further provided on the outer peripheral circle of the first connecting member 1. The first through hole 11 also penetrates through the connecting plate 12; A second connecting member 2, a second through hole 21 is provided on the second connecting member 2. A second thread portion 211 is formed at one end of the second through hole 21; The second connecting member 2 is connected to the first connecting member 1 through the cooperation of the second threaded portion 211 and the first threaded portion, and a clamping and sealing space is formed between the second connecting member 2 and the connecting plate 12.

[0039] The clamping and sealing space is configured to clamp the pipe wall of the main water supply pipe.

[0040] Specifically, for the soft belt quick-connect joint, one end of the first connecting member 1 is provided with a connecting plate 12, and an insertion portion 13 extending outward is further provided at the edge of the connecting plate 12. The size of the insertion portion 13 is smaller than the size of the opening 31 of the main water supply pipe 3. In this way, during on-site installation, the insertion portion 13 can be easily inserted into the opening 31 for guidance. After the insertion portion 13 is inserted into the opening 31, the first connecting member 1 is further rotated so that the connecting plate 12 rotates into the opening 31 and finally the connecting plate 12 is located inside the main water supply pipe 3 and abuts against the inner pipe wall of the main water supply pipe 3. The second connecting member 2 is externally threaded on the main water supply pipe 3 through the second threaded portion 211 and cooperates with the external thread on the first connecting member 1 to thread-fix the second connecting member 2 on the first connecting member 1. After the second connecting member 2 is tightened to the first connecting member 1, the end face of the second connecting member 2 opposite to the connecting plate 12 will press against the pipe wall of the main water supply pipe 3. In this way, the pipe wall of the main water supply pipe 3 near the outer periphery of the opening 31 is squeezed between the connecting plate 12 and the end of the second connecting member 2, thereby realizing the sealing treatment of the opening 31 of the main water supply pipe 3.

[0041] During daily use, since the soft belt quick-connect joint can be assembled on the main water supply pipe 3 on-site, in this way, according to the irrigation requirements of different regions, holes can be directly drilled in the main water supply pipe 3 on-site to form openings 31. Then, the first connecting member 1 is guided through the insertion portion 13 so that the connecting plate 12 is inserted into the main water supply pipe 3, and then sealed and fixed by the second connecting member 2, and the irrigation branch pipe can be connected through the soft belt quick-connect joint.

[0042] Further, in order to facilitate the operator to accurately and smoothly insert the insertion portion 13 into the opening 31 of the main water supply pipe 3, the insertion portion 13 has a pointed head structure, and an inclined surface 14 is formed on one side of the insertion portion 13.

[0043] Specifically, the insertion portion 13 has a pointed head structure along its outward extending direction. In this way, during the operation by the operator, the insertion portion 13 can accurately insert into the opening 31 through the pointed head at its head.

[0044] Among them, during the rotation of the first connecting member 1, an inclined surface 14 is formed on the side of the insertion portion 13 that is squeezed by the edge of the opening 31. By using the guiding of the inclined surface 14, the first connecting member 1 can rotate more smoothly during the rotation process, so as to smoothly rotate the connecting plate 12 into the opening 31, improving the convenience of operation.

[0045] In addition, the inclined surface 14 is configured to guide the insertion portion 13 to be spirally inserted into the water supply pipe in a direction inclined to the center line direction of the opening 31 of the main water supply pipe 3. Specifically, when the first connecting member 1 is connected to the opening 31 of the main water supply pipe 3, the first connecting member 1 first makes the insertion portion 13 inserted into the opening 31 in an inclined manner. For the added inclined surface 14, it can guide the pipe wall around the opening 31 of the main water supply pipe 3 to slide well to the upper surface of the connecting plate 12 during the inclined rotation process, so as to reduce the excessive force on the edge of the opening 31 and prevent it from being damaged during the rotation process. Using the rotation guiding method of an automobile tire sleeved on a wheel hub, the large-sized connecting plate 12 can be inserted into the small-sized opening 31, ultimately meeting the requirements of on-site drilling and installation.

[0046] Furthermore, in order to facilitate the operator to apply a rotational driving force to the first connecting member 1, the cross-sectional shape of the first through hole is non-circular.

[0047] Specifically, the cross-section of the first through hole is non-circular. In this way, during the process of rotating the first connecting member 1, a tool can be inserted into the first through hole to apply an external force. For example, the cross-section of the first through hole can be a plum blossom shape, a triangle or a rectangle, etc.

[0048] Still further, a dial 23 is provided on the outer wall of the second connecting member 2.

[0049] Specifically, during the process of tightening the second connecting member 2, the operator can apply a rotational driving force to the second connecting member 2 through the dial 23, so as to facilitate the operator to install the second connecting member 2 without tools.

[0050] Yet further, in order to meet the requirements of an external irrigation branch pipe, a third internal thread hole 212 is provided at the other end of the second through hole 21. The third internal thread hole 212 is coaxially arranged with the second thread portion 211, and the aperture of the third internal thread hole 212 is larger than the aperture of the second thread portion 211.

[0051] Specifically, the third internal threaded hole 212 is used to meet the connection requirements of the external irrigation branch pipe. The design with the aperture of the second threaded portion 211 being smaller than that of the third internal threaded hole 212 ensures that the second connector 2 can be tightly screwed and assembled in place during the process of screwing the second connector 2 onto the first connector 1, thereby ensuring the sealing connection reliability between the soft belt quick-connect joint and the main water supply pipe 3. For example, a multi-way pipe 4 for connecting the irrigation branch pipe is threadedly connected to the third internal threaded hole 212.

[0052] Furthermore, to meet the requirements of the external irrigation branch pipe, a multi-way pipe 4 integrally formed is also provided at the end of the second connector 2 away from the first connector 1.

[0053] Specifically, a multi-way pipe 4 integrally formed is provided on the second connector 2, and the multi-way pipe 4 can meet the requirements for connecting to the external irrigation branch pipe.

[0054] Embodiment 3: Based on the above Embodiment 1 and Embodiment 2, in another embodiment of the present application, the present application further provides an irrigation system, including a main water supply pipe 3 and multiple irrigation branch pipes (not shown). A plurality of openings 31 are provided on the main water supply pipe 3, and a soft belt quick-connect joint is provided in each opening 31. The insertion portion 13 of the first connector 1 of the soft belt quick-connect joint is inserted into the opening 31, the connecting plate 12 of the first connector 1 abuts against the inner pipe wall of the main water supply pipe 3, and the pipe wall of the main water supply pipe 3 around the opening 31 is clamped in the clamping and sealing space of the soft belt quick-connect joint; the irrigation branch pipe is connected to the second connector 2 of the corresponding soft belt quick-connect joint.

[0055] Furthermore, to facilitate the installation of the irrigation branch pipe, the irrigation system further includes a multi-way pipe 4. The multi-way pipe 4 includes an installation joint 41 and at least one external connection joint 42. The external connection joint 42 communicates with the installation joint 41. The installation joint 41 is provided in the second through hole 21 of the second connector 2, and the irrigation branch pipe is connected to the corresponding external connection joint 42.

[0056] Specifically, to reduce the number of openings 31 and meet the installation requirements of multiple irrigation branch pipes, the irrigation branch pipes to be installed on the soft belt quick-connect joint are transitionally connected through the multi-way pipe 4. During the connection process, the multi-way pipe 4 is threadedly connected to the third internal threaded hole 212 through the installation joint 41, and the irrigation branch pipe can be installed on the corresponding external connection joint 42.

[0057] To improve the connection reliability, the sealing connection method between the external connection joint 42 and the irrigation branch pipe can adopt a conventional pipeline quick-connection method. For example, the external connection joint 42 is further provided with a locking sleeve 43. The irrigation branch pipe is inserted on the external connection joint 42, and the irrigation branch pipe is sealed and clamped between the external connection joint 42 and the locking sleeve 43.

[0058] Specifically, when assembling the irrigation branch pipe, the pipe orifice of the irrigation branch pipe is sleeved outside the external joint 42 and inserted into the locking sleeve 43. Then, the locking sleeve 43 moves outward in cooperation with the thread on the surface of the external joint 42, so that the end of the irrigation branch pipe is pressed between the locking sleeve 43 and the external joint 42.

[0059] Based on the above irrigation system, the present application also provides an assembly method for the irrigation system, including: The connecting plate of the first connector is abutted against the inner wall of the active water pipe, and the first threaded portion is aligned with the opening of the main water supply pipe; holes 31 are drilled in the main water supply pipe 3. Specifically, the positions of the holes 31 on the main water supply pipe 3 can be set according to the distribution positions of the on-site irrigation areas, so that the holes 31 can be as close as possible to the irrigation areas to shorten the overall service length of the irrigation branch pipes.

[0060] The second connector is threadedly connected to the first threaded portion through the second threaded portion, and the pipe wall of the main water supply pipe is hermetically clamped between the second connector and the connecting plate.

[0061] Specifically, based on the structure of the soft belt quick-connect joint in Embodiment 1, the connecting plate of the first connector is abutted against the inner wall of the active water pipe by means of adhesion or welding.

[0062] Based on the structure of the soft belt quick-connect joint in Embodiment 2, the first connector 1 inserts the insertion portion 13 into the hole 31 in a state inclined relative to the hole 31. Then, the first connector 1 is rotated so that the connecting plate 12 rotates into the hole 31 and abuts against the inner pipe wall of the main water supply pipe 3. Specifically, after the hole 31 is drilled, the first connector 1 is installed on-site into the corresponding hole 31. Therefore, how to conveniently install the first connector 1 is the key to determining whether the technology can be popularized. During the process of installing the first connector 1 into the hole 31, the insertion portion 13 is used for guiding, and the first connector 1 is gradually rotated so that the connecting plate 12 is screwed into the hole 31, and finally the connecting plate 12 abuts against the inner pipe wall of the main water supply pipe 3. Preferably, by providing an inclined surface 14 on the insertion portion 13, during assembly, the first connector 1 is first arranged obliquely and the insertion portion 13 is inserted into the hole 31. Then, during the process of rotating the first connector 1, as the connecting plate 12 gradually enters the main water supply pipe 3, the first connector 1 is gradually flattened. Finally, the connecting plate 12 completely enters the main water supply pipe 3 and abuts against the inner pipe wall of the main water supply pipe 3.

[0063] Threadedly connect the second connector 2 to the first connector 1, and seal and clamp the pipe wall of the main water supply pipe 3 between the second connector 2 and the connecting plate 12. Specifically, after the first connector 1 is inserted into the opening 31, the second connector 2 is threadedly tightened onto the first connector 1 and the area around the opening 31 is sealed.

[0064] Finally, connect the irrigation branch pipe to the corresponding second connector 2.

[0065] By providing a connecting plate on the first connector and an outwardly extending insertion portion on the connecting plate, during use, the operator can drill a hole in the main water supply pipe according to the irrigation requirements at the construction site to form an opening. Then, insert the insertion portion of the first connector into the opening and rotate it. Relying on the guidance of the insertion portion, the connecting plate can be rotated into the main water supply pipe and abutted against the inner pipe wall of the main water supply pipe. Then, threadedly connect the second connector to the first connector. At this time, the pipe wall of the main water supply pipe surrounding the opening will be sealed and clamped between the second connector and the connecting plate to seal the opening. The irrigation branch pipe can be connected to the corresponding second connector to communicate with the main water supply pipe to achieve water supply; since the first connector can be installed on the main water supply pipe on-site, it is convenient for the operator to install on-site. In this way, the soft belt quick-connect joint can be installed by drilling holes at the corresponding positions of the main water supply pipe according to the distribution requirements of the actual irrigation area, which is convenient for the operator to assemble the soft belt quick-connect joint to the main water supply pipe on-site, improving the convenience of on-site installation, and further improving the flexibility and convenience of use.

[0066] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
